Animals Without Backbones Science Paperback Book by Ralph Buchsbaum Pelican 1971
(Animals Without Backbones #1)

ELEMENTARY and general accounts of the invertebrates, suit- able for the beginning college student or layman, have been limited to two sorts of books: natural histories, which describe the habits of a great many animals but are lacking in descriptions of basic structure and in theory, and formal textbooks, which are packed with morphological detail and technical terminology.

This book is an attempt to present the main groups of invertebrate animals in simple nontechnical language. 

Each group is used to illustrate some principle of biology or some level in the evolution of animals from simple to complex forms. 

Book is in acceptable condition. General shelf and corner wear. Some light staining on interior and exterior. A few white marks on front and back cover. The spine has some issues (see photo #3). Staining on the front and back cover. Cover creasing. A solid reading copy. Please see photos for details, and let me know if you have any questions.
